+         * elements are discussed below.
+         *
+         * <h3>Appender configuration</h3>
+         *
+         * Appender configuration syntax is:
+         * <pre>
+         * # For appender named <i>appenderName</i>, set its class.
+         * # Note: The appender name can contain dots.
+         * log4cplus.appender.appenderName=fully.qualified.name.of.appender.class
+         *
+         * # Set appender specific options.
+         * log4cplus.appender.appenderName.option1=value1
+         * ...
+         * log4cplus.appender.appenderName.optionN=valueN
+         * </pre>
+         *
+         * For each named appender you can configure its {@link Layout}. The
+         * syntax for configuring an appender's layout is:
+         * <pre>
+         * log4cplus.appender.appenderName.layout=fully.qualified.name.of.layout.class
+         * log4cplus.appender.appenderName.layout.option1=value1
+         * ....
+         * log4cplus.appender.appenderName.layout.optionN=valueN
+         * </pre>
+         *
+         * <h3>Configuring loggers</h3>
+         *
+         * The syntax for configuring the root logger is:
+         * <pre>
+         * log4cplus.rootLogger=[LogLevel], appenderName, appenderName, ...
+         * </pre>
+         *
+         * This syntax means that an optional <em>LogLevel value</em> can
+         * be supplied followed by appender names separated by commas.
+         *
+         * The LogLevel value can consist of the string values FATAL,
+         * ERROR, WARN, INFO, DEBUG or a <em>custom LogLevel</em> value.
+         *
+         * If a LogLevel value is specified, then the root LogLevel is set
+         * to the corresponding LogLevel.  If no LogLevel value is specified,
+         * then the root LogLevel remains untouched.
+         *
+         * The root logger can be assigned multiple appenders.
+         *
+         * Each <i>appenderName</i> (separated by commas) will be added to
+         * the root logger. The named appender is defined using the
+         * appender syntax defined above.
+         *
+         * For non-root loggers the syntax is almost the same:
+         * <pre>
+         * log4cplus.logger.logger_name=[LogLevel|INHERITED], appenderName, appenderName, ...
+         * </pre>
+         *
+         * The meaning of the optional LogLevel value is discussed above
+         * in relation to the root logger. In addition however, the value
+         * INHERITED can be specified meaning that the named logger should
+         * inherit its LogLevel from the logger hierarchy.
+         *
+         * By default loggers inherit their LogLevel from the
+         * hierarchy.  However, if you set the LogLevel of a logger and
+         * later decide that that logger should inherit its LogLevel, then
+         * you should specify INHERITED as the value for the LogLevel value.
+         *
+         * Similar to the root logger syntax, each <i>appenderName</i>
+         * (separated by commas) will be attached to the named logger.
+         *
+         * See the <a href="../../../../manual.html#additivity">appender
+         * additivity rule</a> in the user manual for the meaning of the
+         * <code>additivity</code> flag.
+         *
+         * The user can override any of the {@link
+         * Hierarchy#disable} family of methods by setting the a key
+         * "log4cplus.disableOverride" to <code>true</code> or any value other
+         * than false. As in <pre>log4cplus.disableOverride=true </pre>
+         *
+         * <h3>Example</h3>
+         *
+         * An example configuration is given below.
+         *
+         * <pre>
+         *
+         * # Set options for appender named "A1".
+         * # Appender "A1" will be a SyslogAppender
+         * log4cplus.appender.A1=log4cplus::SyslogAppender
+         *
+         * # The syslog daemon resides on www.abc.net
+         * log4cplus.appender.A1.SyslogHost=www.abc.net
+         *
+         * # A1's layout is a PatternLayout, using the conversion pattern
+         * # <b>%r %-5p %c{2} %M.%L %x - %m\n</b>. Thus, the log output will
+         * # include # the relative time since the start of the application in
+         * # milliseconds, followed by the LogLevel of the log request,
+         * # followed by the two rightmost components of the logger name,
+         * # followed by the callers method name, followed by the line number,
+         * # the nested disgnostic context and finally the message itself.
+         * # Refer to the documentation of {@link PatternLayout} for further information
+         * # on the syntax of the ConversionPattern key.
+         * log4cplus.appender.A1.layout=log4cplus::PatternLayout
+         * log4cplus.appender.A1.layout.ConversionPattern=%-4r %-5p %c{2} %M.%L %x - %m\n
+         *
+         * # Set options for appender named "A2"
+         * # A2 should be a RollingFileAppender, with maximum file size of 10 MB
+         * # using at most one backup file. A2's layout is TTCC, using the
+         * # ISO8061 date format with context printing enabled.
+         * log4cplus.appender.A2=log4cplus::RollingFileAppender
